Baked teriyaki salmon is a quick and easy weeknight dinner that's both nutritious and flavorful. Salmon fillets are coated in a homemade teriyaki sauce and baked in the oven until perfectly flaky and tender.
Preheat oven to 400 degrees Fahrenheit. Lightly grease a wide, 2-quart baking dish (7x11 in size or similar) and set aside.
If needed, slice salmon into four even fillets, check for pin bones, then place side-by-side in prepared baking dish.
In a bowl, add soy sauce, water, vinegar, brown sugar, cornstarch, sesame seeds, garlic, ginger, and red pepper flakes. Whisk until incorporated. Pour sauce over salmon fillets.
Bake salmon, uncovered, for 12-15 minutes, or until salmon flakes easily in the center (times may vary based on thickness of salmon).
Garnish with diced green onion and serve.
Notes
Leftovers will keep in the refrigerator for 3-4 days in a tightly sealed container.
Sauce portion of the recipe can easily be doubled if serving with plain white rice, noodles, or steamed veggies.
